素晴らしいスクリプトありがとうございます。この中で使われている xpath コマンドの由来が分からなかったのですが、何由来か分かりますでしょうか。多分何らかのPerlモジュールから入ったものと思うのですが…。Debian系OSであれば dpkg -S $(which xpath) すると調べられると思います。
I thanks to this awesome script! I wonder
xpathcommand using in this script. Where is this command from? If you use Debian like OS, you can lookdpkg -S $(which xpath).
